Grease is always a problem, what was once tried here was to dip a hard med/small paintbrush into a cup containing hot water and a good squeeze of detergent concentrate, and holding the keyboard upside down, run the brush slowly around the keys. Solvents might be a bit risky. Keep keyboard upside down until dry, and clean up with a soft cloth steeped in methylated spirits.
Still use any of the four monitors from the old system – are they all 24″. Quite like 1440X900 on the 27″, depth enough without being too wishy washy. the integrated graphics doesn’t provide much support for sizing the viewport to the screen, so back to fiddling with the monitor controls. 😛
